A weed that grows when the wind blows. Usually grown in the southern states, it has been known to grow well north of New Jersey. Dick weed spreads very easily from area to area, and can grow to huge sizes. It is best not to plant Dick Weed to close to Pussy Willows, otherwise you may get a crop of cumquats.
Look at all the Dickweeds out there!!

Someone who is as irritating as a weed growing in your dick would be. Especially within a short amount of time of being around that person. Usually someone that you know but is truly more accurate when used on a stranger that manages to accomplish said irritation.
Joel is such a dickweed, he hasn't even been home for five minutes and I want to kill him.
